The invention is exemplified in a machine which comprises a driven arbor 24 for a core a (Fig. 3) on which wires are to be wound, and a reciprocable carriage b, which carries suitable guides for directing the wires from suitable sources of supply, such as reels c (Fig. 4) onto the core a. It is to be understood that the machine may be equipped with wire-guides for simultaneously winding any desired number of coils on any suitable core or cores on the arbor 24. The machine comprises a suitable frame 20 (Fig. 1), a supplemental base 2|, and a gear case or housing 22 rigidly secured together. The carriage b for the wire-guides is supported on the frame 20 and in the case 22. Variable speed gearing for reciprocating carriage b, mechanism for variably controlling the speed of travel of said carriage, mechanism for controlling the range of travel or length of thestrokes of said carriage, and mechanism for controlling'the number of revolutions of the arbor 24, are enclosed in gear-case 22. The core a on which the wire is to be wound is applied to arbor 24 in any manner so as to rotate therewith to wind the wires on the core. Arbor 24 is threaded to a couplingcollar 28 (Fig. 9) which is journaled in a sleevesection 29 and engages the inner race of a combined radial and thrust anti-friction bearing 25. A drive shaft 34 coaxial with arbor 24 is screwthreaded to the collar 28. A collar 35 is screwthreaded to shaft 34 and has an abutment for the inner race of the bearings 25, so that this race will be secured to the collars 35 and 28 and the shaft 34. The outer race of bearing 25 is clamped between a sleeve-section 30 and the sleeve-section 29 which are screw-threaded to each other. Sleeve-section 30 is axially adjustable in and between plates 3| to which the sleevesections are respectively threaded. The sleevesection 3|! and plates 3| are mounted in a standard 26 which is mounted on the top of frame 20. Arbor 24 has its inner end screw-threaded to collar 28 so that it can be removed and replaced so that arbors of different diameters may be connected to the collar 28. By rotating the plates 3| around the sleeve-sections 29, 38 to which they are screw-threaded, the arbor 24 may be axially adjusted. A screw-collar 32 serves to clamp the core a longitudinally for rotation with the shaft 34'. The outer end of arbor 24 is journaled in a suitable tail-stock 21 (Figs. 3 and 4) which is slidably mounted in any suitable manner on the frame 20 to permit it to be disconnected from the spindle for placement of the empty cores on the arbor and the removal of cores with coils thereon. Drive-shaft 34 (Fig. 9) extends longitudinally through a driving sleeve 36, to which is secured a belt-pulley 31, which is driven by a belt 38 from any suitable source of power. A handwheel 46, integral with pulley 31, is provided, so that the sleeve 36 may be manually rotated when desired. Sleeve 36 is journaled in a combined radial thrust anti-friction bearing 4|, which is carried in a two-part sleeve 42 in one of the side walls of the gear-case 22. The drive-shaft 34 is driven from the sleeve 36 under control of a clutch comprising a toothed clutch-member 43, which is slidable on and splined to shaft 34 and a clutch-member 44 keyed to the sleeve 36. A shifter-collar 45, controlled by means hereinafter set forth, is adapted to couple and uncouple clutch-members 43 and 44 to control the rotation of the arbor 25 and the core thereon.

The invention includes a revolution-register for the arbor 24, which can be readily set to stop the arbor after any predetermined number of convolutions have been wound on the coils on the core a. This registering mechanism is driven from the shaft 34. The register comprises an annular unit-dial 48, a rotatable index-arm 49, for dial 48, a multiple dial 58, and a rotatable index-arm (Figs, 1 and for dial 50. The outer dial 48 is marked, for example, with 300 indications. each for one revolution of the arbor 24. The dial 50 is marked with, say, 200 graduations, each for indicating the revolutions of arm 49 or 300 revolutions of the arbor 24. A wormwheel 46 (Figs. 2 and 11) is fixed to shaft 34 to drive a worm-gear 41. Index-arm 49 is fixed to rotate with a shaft 54. The gearing which operates shaft 54 and index 49 from worm-gear 41 to register and indicate the revolutions of arbor 24, comprises a pair of differential planetary or epicycloidal pinions 55, 56 which are secured to rotate together and are mounted on studs carried by the worm-gear 41; a pinion 51, the hub of which is fixedly secured in a bracket 58, which is fixedly secured in the gear-case 22, and with which meshes the pinion 56; a sleeve 59, around shaft 54, and extending loosely through the hub of worm-gear 41; a pinion 60, which is integral with sleeve 59 and meshes with the pinions to cause the sleeve to rotate at a low speed by reason of the difference in pitch diameters of the pinions 55, 56, the latter of which meshes with the fixed pinion 51; a clutchmember 6| fixed to the rear end of sleeve 59, which extends through and is journaled in the hub of fixed pinion 51; a coacting clutch-member 62, which is normally held in engagement with clutch-member 6| by a spring 63 and is fixed to the inner end of shaft 54. This gearing causes the index-arm 49 to register the revolutions of the arbor 24 on dial 48. The mechanism for driving the index-arm 5| to register the revolutions in multiples of 300, comprises a pair of arms 65 on a hub which is keyed to rotate with the sleeve 59 through which the unit indexarm is operated; planetary pinions 66 carried by said arms and meshing with a gear-ring 61 which is fixed to a fixed bracket 68; a gear 69, which meshes with the pinions 66 and has a hub journaled in the bracket 68; a clutch-member 16 fixed to rotate with gear 69; a coacting clutchmember 1 I, which is normally spring-pressed into coupled relation with member 16 by a spring 12; a hub 13 on member 1| which is fixed to index-arm 5| and is journaled in a head or plate 14 which is fitted into the front of the gear-case 22 and carries the dials 48, 56. Gear 69 is provided with one more tooth than the gear-ring 61, so that upon each complete revolution of the sleeve 59 which drives the unitindex arm 49, gear 69 and index-arm 5| will be advanced a distance corresponding to one of the multiple-indications on dial 56 and register the multiple-indications on dial 50. The number of teeth provided on the fixed gear 69 corresponds to the number of divisions on the dial 50 and the number of teeth in gear 61 is one less and, as a. result, index-arm 5| will be operated to register the revolutions of the unitdial or, for example, the revolutions of the arbor 24 in multiples of 300. The register-mechanism is adapted to automatically stop the machine by uncoupling the clutch 43, 44, between the drivingsleeve 36 and the spindle 34. A forked lever 16 (Figs. 12 and 13) is pivoted, as at 11, to the collar 45 around clutch-member 43. Lever 16 is fulcrumed at 18 in lugs projecting from a bracket 19 which is fixed in the gear-case 22.

A block has trunnions 80 pivotally held in the upper end of lever 16. A double arm 83 is fixed to a shaft 84. The lower end of arm 86 is pivotally connected to operate lever 16 to positively uncouple clutch 43, 44 by a link-pin 8|, which is slidably mounted in block 80 and has trunnions at its rear end which are pivoted in the lower end of lever 83. An abutment-nut 8| on the front end of link-pin 8| engages the front of block 80, and a spring 8| is interposed between the block and arm 83. When arm 86 is shifted in one direction, it will positively rock lever 16 to uncouple clutch 43, 44. When said arm is moved in the opposite direction, it will, through spring 8| yieldingly shift lever 16 to couple the clutch-members. A spring 96 between arm 83 and gear-case 22 is applied to rock shaft 84 so abutments 88 will bear against clutchmembers 1|, 62,. and to rock the shaft to uncouple clutch 42, 43 when the abutments 88 pass into notches 89.

A pair of trip-arms 86, 81 are fixedly secured to the shaft 84 of arm 83 and each of said arms is provided at its free end with an abutment 88. Clutch-member 62, through which the unit indexarm 49 is driven, and clutch-member 1|, through which the multiple index-arm 5| is driven, are each provided with a notch 89. Trip-arm 81 rides on the periphery of clutch-member 1| and trip-arm 86 rides on the periphery of clutchmember 62. When the notches 89, in the course of the rotation of clutch-members 1|, 12, register with the abutments 88 on trip-arms 86, 81, the abutments will drop into the notches and said arms will be shifted to rock shaft 84 and arm 86 to uncouple the clutch 43, 44. When the abutments 88 of trip-arms 86, 81 are lifted by the periphery of clutch-members 1|, 62, shaft 84 will be held in position to hold the clutch members 43, 44 coupled.

The number of revolutions of the spool spindle or convolutions of wire on the spool for each winding operation before the machine is automatically stopped, may be varied to any desired predetermined number of revolutions within the range of the indicator-dials. The clutch-mermber 62 may be rotatably set to bring its notch 89 any desired distance from abutment 88 of arm 86 when member 62 is uncoupled from its coacting member 6|. Clutch-member 1| may be rotatably adjusted to bring its notch 89 any desired distance from the abutment 88 on trip-arm 81 when member 1| is uncoupled from its coacting member 18. A stop 48 is adlustably secured by screws in an undercut channel II in the front of dial-plate of head 14. This stop (Figs. 14 and 18) carries a pivoted spring-pressed dog 49", which permits the index-arm 49 to slip under the stop while it is being operated in one direction by the gearing. A stop 8i- (Fig. 11) is adiustably secured in an annular channel 92 in the hub or plate 11. These stops can be set at any of the indications on the respective dials according to the desired number of revolutions of the arbor 24. When the index-arms 49, 8| of the register are at the zero indications on the dials 48, 88, respectively, the notches 89 in clutch-members 82, 1I will be positioned to trip the controlling mechanism for the clutch 48, 44. To set the machine for any desired number of convolutions of wire on the core a, the operator will set the stops 49 and 8I at points corresponding to the number of convolutions desired. When the index-arms are moved against the stops, the machine will operate through clutch 48, 44 until the index arms both reach the zero indication, at which time the notches 89 will both be positioned to trip the arms 88 and 81 and uncouple clutch 43, 44.

When a change in the setting of the indexarms 49, 8I is desired, they are uncoupled from their driving mechanism. For this purpose, clutch 18, 1I, through which index-arm 8I is operated around dial 88, and clutch GI, 82', through which index-arm 49 is operated around dial 48, are uncoupled and locked in uncoupled position, so the index-arms will be rotatable independently of their driving mechanism. The

mechanism for this purpose comprises a handle 2I8 (Figs. 1 l0 and 12) on a shaft 2I1, which is journaled in the gear-case; a bevel-pinion 2l8 fixed to shaft 2"; a bevel-gear 2I9 meshing with gear 2! and fixed to a stud 228, which is journaled in a plate 22 I, which is fixed to the bracket 19; a pair of oppositely extending arms 222 (Fig. 12) fixed to shaft 228; a pair of slides 228 pivoted to arms 222 and slidably mounted on the bottom of plate 22 I, a forked lever 224 pivoted to bracket 88 and adapted to engage clutch-member 82 to disengage it against the force of spring 83 from driving-member BI; a similar lever 228 pivoted to bracket 68 and adapted to disengage against the force of spring 12 the clutch-member H from the driving-member 18. Slides 228 are provided with hooks 228 for engaging the upper ends of levers 224 and 228 when the handle 2 I8 is turned to move said ends together. and uncouple said clutches. A cam 221 (Figs. 2, l0 and 12) is fixed to the shaft 2I1 of handle 2I8 to engage an arm 228 which is fixed to the shaft 84 of the devices for operating the trip-arms 88, 81 (Fig. 13), which control the starting and stopping of the machine.

When the handle 2I8 is shifted from its normal position, shown in Fig. 1, the index-arms of the revolution-counters will be uncoupled from their driving mechanism and will be free for settings at different points on their dials.

The reciprocable carriage b is provided with arms 98 for separately guiding wires longitudinally of the core, so that the convolutions will be closely and evenly wound. Any desired number of these arms, according to the number of coils to be wound during each operation, may be provided. The carriage b comprises a pair of rods 98 and 91, which are slidably mounted in a wall of the gear-case 22 and a fixed bracket 88; a crosshead 94 in the gear-case 22 in which the inner ends of rods 98 are fixedly secured; a pair of brackets 88 fixed to rods 88, 81; and a shaft I88 mounted in the upper end of brackets 88 to which the guide-arms 88 are individually clamped for relative adjustment. The shaft I88 is pivotally mounted in brackets 88, so the arms 88 can be swung upwardly to provide access to the coils on the core when desired, and is provided with suitable locking means, such as a screw-wheel I8 I for securing shaft I88 and arms 98 in their operative position. Grooved guide-wheels I82 are carried at the free ends of arms 88 for guiding the wire from reels 0 (Fig. 4) which are usually placed in the rear of the machine.

The mechanism for reciprocating the carriage b comprises a shaft I88 (Figs. 6 and 7) which is journaled in a bracket I88 in the gear-case 22, and an antifriction combined radial and thrust-bearing I88; a screw I81 which is threaded to a nut I89, which is fixedly secured to the carriage-head -84 and against rotation by a boxing II8, which is secured to said head; and reversible gearing for rotating the screw III1 in opposite directions to reciprocate the carriage b. This reversible gearing comprises a shaft III, which is iournaled in a bearing-bracket II2 (Fig. 6); a gear II8 fixed to and for driving said shaft III; a bevel gear II4 fixed to shai't'III and provided with a clutch-member II8; an oppositely facing, bevel gear II8, which is loosely mounted on the shaft I88 and is provided with clutch-teeth II1; an intermediate bevel gear II8 Journaied on a fixed stud H8 and meshing with gears H4, H8, and a clutch-sleeve I28, which is splined to and slidable on the shaft I88 and is provided with clutch-teeth at its opposite ends to mesh with the clutch-members H8 and H1, respectively. When the clutchsleeve I28 is coupled to the bevel-gear II4, shaft I88 and screw I81 will be driven in one direction directly from the gear I I4. When the sleeve I28 is disengaged from the gear I I4 and engaged with clutch-teeth III, shaft I88, screw I81 will be driven in the opposite direction through intermediate gear II8, bevel gear IIS and clutchsleeve I28. The sleeve I28 is automatically shifted and controlled by mechanism hereinafter described to reciprocate the carriage for the wire guides.

The invention contemplates variation of the relative speed of travel of the carriage b according to the gauge of the wire to be wound on the core. For this purpose, variable speed mechanism is provided whereby the speed of the mechanism, including screw-shaft I81, may be varied so that the travel of the carriage during each revolution of the spools, will correspond substantially to the gauge of the wire being wound on the core. This mechanism comprises (Figs. 2 and 5) a gear I22 (Fig. 2) secured to the inner end of the shaft 84, which drives and rotates with the arbor 24; a gear I28, which meshes with gear I22; a pinion I28, which is connected by a sleeve I24 with gear I28; a gear I28, meshing with gear I28 and loosely mounted on a shaft I29, which is journaled in suitable bearings in the gear-case; a gear I38, which meshes with pinion I28 and is loosely mounted on shaft I29; a clutch-sleeve I8I, which is slidable on and splined to shaft I28, and is adapted to be coupled to either of the gears I28, I21 to drive shaft I29 at two different speeds; a gear I82 fixed to the inner end of shaft I28; a gear I38, which meshes with gear I82 and is fixed to a shaft I84, which is suitably journaled in the gear-case 22; a clutch-sleeve I88 which is splined to and rotatable with shaft I84; gearsv I88 and I81, which are loosely mounted on shaft I34, adapted to be separately coupled to and driven by said shaft through sleeve I 35, and are of different diameters; a gear 138, which meshes with gear I36 and is fixed on a sleeve I39; 3 gear I40, which meshes with gear I31; gears HI and I42 of different diameters, which are fixed to rotate with gears I38, I40; a set of gears I43, I44 and I45, which are fixed to a sleeve I46, which is splined to, and slidable on, a shaft I41, so that gear I43 may be slipped into engagement with gear I42, gear I44 may be slipped into engagement with gear I 4|, and gear I45 may he slipped into engagement with gear I38 to drive shaft I41 at different speeds relatively to shaft I34; a sleeve I48. which is splined to, and slidable on, shaft I41 and has affixed thereto gears I49, I50 and I5I; a sleeve I52, which has affixed thereto a gear I53 adapted to mesh with gear I46, 3. gear I54 adapted to mesh with gear I50, and a gear I55 adapted to mesh with gear I5I; and an idler gear I56 (Fig. 6), which meshes with gear II3 on shaft I I I. A fork I51 is adapted to shift clutchsleeve I3I between gears I26 and I30 and is fixed to a rock-shaft I58, which extends through the front of the gear-case 22 and is provided with a handle I59 whereby the fork may be shifted to couple the shaft I29 so it will be driven at different speeds by gear I30 or pinion I26 to vary the speed of the entire gear-train driven from shaft I29. A forked lever I60 is adapted to shift the clutch-sleeve I35 to couple gear I36 or gear I31 to the shaft I34 and is pivoted in a bracket I6I in the gear-case. A handle I62, pivotally mounted in the front of the gear-case, operates 8. lug or arm I63 (Fig. 5) to shift lever I60. By shifting the clutch-sleeve I35, the set of gears I38, I, I42, I40 may be alternately driven at two different speeds to correspondingly vary the speed of the gear-train driven thereby. A fork I64 is provided for shifting sleeve I46 and gears I43, I44, I45 on shaft I41 for engagement, respectively, with gears I42, MI and I38, inner end of a shaft I65, to the front end of which a handle I66 is fixed. This handle may be set in any of three positions for respectively engaging the gear-pairs. By this, the shaft I41 may be driven at three different speeds relatively to shaft I34 to correspondingly vary the gear-train driven by shaft I41. A fork I61 for shifting sleeve I48 and gears I49, I50 and I5I, is fixed to the inner end of a rock-shaft I68, to the'front end of which a handle I69 is secured, so that the sleeve I52, which carries gears I53, I54, I55, may be driven at three different speeds relatively to shaft I41, to correspondingly vary the speed of gears I56, I I3 and shaft III, through which the carriage for the wire-guides is shifted longitudinally. By means of various settings of the handles I59, I69, I62, I65, or any permutations thereof, the speed of travel of the wire-guide carriage relatively to the speed of rotation of the spools on which the wire is being wound, may be varied to correspond to the different gauges of wire used in winding coils for different uses or purposes. This exemplifies variable speed mechanism for this purpose, which is readily controllable so that the machine may be quickly set for winding different gauges of wire on the spools.

The machine is adapted for winding coils of different lengths. For this purpose, mechanism is provided for automatically shifting the clutchsleeve I 20 to impart strokes of variable length to the carriage b according to the length of the coils desired. This mechanism comprises a worm "I, which is fixed to the shaft I05 (Figs. 6, 7 and and is fixed to the ible shaft I05. Cam I8I 9') a worm-gear I12 engaged by said worm and fixed to a shaft I12, which is journaled in an upstanding lug on bracket I06; a pinion I13 fixed to rotate with shaft I12 and a worm-gear I12; 9. gear I14 (Figs. 5' and 8); a shaft I15 journaled in a bracket I15 fixed in the gear-case 22, and to which gear I14 is fixed; a clutch comprising a member I18 fixed to shaft I15 and a coacting member I 11, which is connected to drive a sleeve I18 which is journaled in a plate or head I19 in the front of the gear-case 22; an indexarm I, which is fixed to rotate with sleeve I18 and member I11; a cam I8I, on the back-face of clutch-member I11 and adapted to be rotatively adjusted by the arm I80; and a cam I82, which is fixed to a hub which is fixed to rotate with shaft I15. Cams I82, I8I rotate with the driven shaft I15 to control the reversible gearing for reciprocating the wire-guide carriage. Cam It is rotatively adjustable relatively to cam I82 to vary the length of the strokes of said carriage. A shifter-collar I83 (Fig. 5) is adapted to slide clutch-sleeve I20 into engagement with either of the gears H4, H6 to drive shaft I05 and screw I01 in opposite directions. A lever I84, for shifting collar I83, is fulcrumed at I85 and is provided with an abutment I86 (Fig. 5). A pair of rods I81 are adjustably secured to projecting lugs on collar I83, are slidable in and through bracket I06, and are cross-connected by a bar I88. Springs I89 are applied between bracket I06 and collars I89, which are shouldered against, and slidable in, the crossbar I88 to exert pressure to the right on crossbar I88 and shift, through rods I81, collar I83 and clutch-sleeve I20 to engage said sleeve and bevelled gear II6 when the lever I84 is released by the controlling mechanism for said lever. Collar I83 is reversely shifted to engage sleeve I20 and bevelled gear II4, by a pair of abutment collars 200, which are carried by a pair of rods' 200. The outer ends of rods 200 are fixedly secured in the crosshead 94 of the carriage b, so they will reciprocate with the carriage and their inner ends are slidable through collars I89 in crossbar I88 and are slidable in the bracket I06. Springs I90 are interposed between washers I90, which bear against collars 200 and the crosshead 94. Collars 200 are fixedly connected to rods 200. During the instroke of the crosshead 94, collars 200 engage the collars I89 to relieve the crossbar I88 from the pressure of springs I89. Thereafter, the spring-pressed washers I 90 engage the crossbar I88 to apply released by its controlling mechanism. This spring-pressed means for shifting the clutch-sleeve I20 of the reversible gearing exemplifies a construction by which springpressure will be applied to said sleeve before the controlling mechanism releases the lever I84 for its respective movements for a quick and accurate timing of clutch-sleeve I20 in the reciprocations of the carriage b.

An abutment-arm 205 (Figs. 5, 8 and 9), controlled by rotatabie cam I82, and an abutment.- arm 204, controlled by cam I8 I, control the movements of lever I84 and clutch-sleeve I20 at the ends of the in and out-strokes of the carriage b. These abutment-arms alternately lock and release said lever under control of said cams. Cam I82 is fixed on a hub which rotates with the shaft I15 which is driven by gear I14 from the reversis on clutch-member I11, which is secured to arm I80 and is driven by clutch-member I18 on shaft I18. illhe reverse movements of shaft I88 conjointly rotate shaft I15 and cams I82 and I8I in opposite directions to cause the cams to alternately shift the rockerarms 284, 285 to release lever I84 for the movements of clutch-sleeve I28, and to lock it in shifted positions at the end of the in and out-strokes of the carriage 1). Cam I82 engages an arm 288 on a rocker 282, to which abutment-arm 288 is secured. A spring 2I8 is applied to rocker 282 to press arm 288 towards the face of cam I821 Cam ill on member I11 engages an arm 288 on rocker 282, which is connected by a shaft 282* to the abutment-arm 282. A spring 2 is applied to rocker 282 to shift abutment-arm 284" when lever I84 is shifted into one of its alternate positions. Adjustable stops 28I are provided to limit the movement of lever I84. Shaft 282' is journaled in bearing-brackets 288.

Near the end of each in-stroke of the carriage b, the spring-pressed washers I88, which reciprocate therewith, will, after collars 288- have compressed springs I88, engage crossbar I88, to shift the collar I88 to engage clutch-sleeve I28 and bevelled gear II4 when cam I82 rocks arm 288 and swings abutment-arm 285 clear of abutment I88 on lever I84. Simultaneously, abutmentarm 284 will be rocked by its spring 2 to lock lever I84 to keep the clutch-sleeve so engaged during the out-stroke of the carriage. The outstrolre of the carriage will continue until cam I8I engages arm 288 and shifts abutment-arm 284 to clear abutment I88, at which time lever I84 will be released, so that springs I88 will, through crossbar I88 and rods I81, shift sleeve I28 to engage bevelled gear II8 and, thereupon, the instroke will commence. Simultaneously, spring 2I8 will swing arm 285 into position to engage abutment I88 on lever I84 to hold sleeve I28 thus engaged. The in-stroke of the carriage will continue until the washers I88 exert pressure to the left on crossbar I88 and cam I82 rocks abutment-arm 285 to release lever I84, so that sleeve I28 will again engage bevelled gear II4. 'Ihese reciprocations will continue until the machine is automatically stopped at register-controlled clutch 48, 44.

The invention includes mechanism for readily varying the strokes of the carriage by rotatably adjusting cam I8I relative to cam I82 to va y the timing of periods of engagement of drivingsleeve I28 withgears H4, H8, respectively. An index-arm 2I2 (Figs. 1 and 8) is keyed to and rotates with shaft I15 and cam I82. Index-arms 2I2 and I88 are rotatable around a dial 2I4 on the front of head I18. A nut 2I8 is adapted to be-tightened, so that arms 2I2, I88 and clutchmembers I15, I11 will be locked together to rotate with shaft I14. The spacing between index-arms I88 and 2I2 and corresponding spacing between cams I82 and III, will control the lengths of the stroke of can'iage b. when a change in the length of the stroke is desired, the operator will loosen nut 2I3, so that index-arm I88, which is fixedly connected to clutch-member I11, which carries cam I8I, can be rotated relatively to its coacting clutch-member I18 to effect a different setting between the index-arms and a corresponding variation in the periods between the movements of the clutch-sleeve I28 of the reverse gearing for reciprocating carriage b. When nut 2I3 is loosened, spring 2I5 will separate clutch-member I11 from member I18, so that the operator can freely adjust cam I8I relatively to cam I82. After this setting has been effected as desired, nut III will be tightened to maintain the desired stroke-lengths of the carriage 17 until change for a variation in the length of the coils is desired. During the operation of the machine, index-arms rotate together and the graduations between arms I88, 2I2 indicate the length of the carriage-stroke for which the machine is set. This exemplifies means which is easily and quickly' adjustable to vary the length of the carriage-strokes.

The operation of the machine will be as follows: The operator will place a core of any suitable type on the spindle 24 by sliding the tailstock 21 into position to permit the core to be secured thereon and then replacing the tail-stock in its operative position. The ends of the wires from the supply reels c will then be directed around the guide-sheaves I82 and secured on the core. The operator will relatively set the indicator-arms I88, 2I2 on the dial 2 to correspond to the stroke of the guide-wires desired, according to the length of the coils desired. In this setting, cam I8I will be rotatably adjusted relatively to cam I82 to vary the timing or periods between the shifting movements of clutch-sleeve I28 of the reverse gearing for operating the guide-carriage. After the setting has been made, nut 2I8 will be tightened to fix the cams in their relative position. The operator will by the selective settings of the control levers' I88, I88, I82 and I88, adjust the speed-change gearing which drives the reversible gearing for reciprocating the guide-carriage to regulate the speed of movement of the carriage according to the gauge of the wire to be wound on the core. The stops 48- and 5i of the revolution-register will be adjusted according to the number of convolutions of wire to be wound on each coil. This will adjust the clutch-members 82, 1I (Fig. 10) to bring the notches 88 therein so that after the desired predetermined number of revolutions of the spindle, the driving clutch 48, 44 for the machine will be uncoupled. The stops 48, 5| will be set away from the zero indicators on dials 48, 58, according to the number of revolutions of the core spindle desired. In making this setting, lever 2 I8 will be shifted to uncouple clutch-members 82, 1I, through which the index-arms 48, 5I are driven, so that said arms can be moved independently of their driving mechanism. The index-arms will be shifted against their respective stops and the handle 2I8 will be returned to its normal position to release clutch-members 82, 1I and couple the arms 48, 5| to. their driving mechanism. The notches 88 in said clutch-members will then be rotated from the zero point to correspond to the number of revolutions of the core desired. As these clutch-members are rotated, the driving-clutch 43, 44 for the machine will be coupled to start the machine. The operation of the machine will continue until the notches 88 on members 82, 1| reach the zero position, when the trip-arms 88, 81 will enter the notches and automatically uncouple the driving clutch and stop the entire machine.

The invention exemplifiies an improved coilwinding machine which can be quickly set to vary the number of convolutions of wire on each coil, the speed of travel of the wire-guide to conform to different gauges of wire to be wound on the core, and the length of the stroke of the wireguides to correspond to the difi'erent lengths of the area of the cores which are covered by the windings. This makes it possible to economically produce coil-windings with any number of convolutions, different gauges of wire and diflerent lengths of spools.
